Endosalpingiosis
Diagnosis in short

Endosalpingiosis. H&E stain.
LM cystic lesion with ciliated epithelium surrounded by fibrous stroma, psammoma bodies
LM DDx endometriosis, serous carcinoma, adenocarcinoma, peritoneal inclusion cyst
Site peritoneum, omentum, lymph node (rare)
Clinical history may be associated with endometriosis; incidental finding
Prognosis benign

Endosalpingiosis is a benign entity that can be confused for cancer.

General

  • Benign entity that may lead to a misdiagnosis of adenocarcinoma[1] or serous carcinoma.
  • The clinical significance of endosalpingiosis is not definitively settled; opinions differ on whether it is:
    1. associated with pelvic pain,[2] or
    2. an incidental finding discovered in the course of investigating something else (pelvic pain, menstrual irregularities, infertility).[3]

Microscopic

Features:[4]

  • Cystic lesions with:
    • Ciliated (tubal type) epithelium, without endometrial stroma.
      • Endosalpingiosis is surrounded by fibrous stroma; tubal type epithelial surrounded by ovarian stroma is a variant of endometriosis.
  • Associated with psammoma bodies.[5]

Notes:

  1. Not associated with hemorrhage.[6]
  2. In a lymph node, endosalpingiosis may be misinterpreted as a metastasis![7]

DDx:[8]
